Old thread but, If you're still having this issue, NDSII (Nissan Data Scan 2) lets you connect into the BCM and SRS systems with a simple K-line interface cable. It wont like the new ecu i'd imagine but its a reliable way to get into your ABS and Safety systems and pull faults / clear faults if you need. I'm sure i have a spare license laying around too if you end up needing a quick way in.
